Drew makes rectangular shoes for his robot. Each shoe has whole number side lengths and an area of 7 square centimeters. What is the total perimeter of both shoes? Is there more than one answer? Why or why not?

The robot is made of rectangles. The side lengths of each rectangle are labeled. Find the perimeter of each rectangle, and record it in the table on the next page.

Give two examples from Mrs. Dutra’s class to show how it is possible to have different areas for rectangles that have the same perimeter.
Did any students in Mrs. Dutra’s class draw a square? Explain how you know.
What are the side lengths of the rectangle that most students in Mrs. Dutra’s class made with a perimeter of 28 centimeters?
